Title: Height shiftable side glazing for automobiles
Inventor: KRAMLING FRANZ
IPC: C03B27/00
Filed: 1991-08-26
Abstract: A vertically adjustable composite motor vehicle side glazing, particularly a door window glazing, is made from composite glass including two 1.5 to 3.5 mm thick thermally tempered individual glazings with a thermoplastic intermediate layer. Each individual glazing has in the marginal area tensile stresses in the core, which in the case of a glazing thickness of 2 mm amount to 54 to 76 MN/m2 and for a glazing thickness of 3 mm amount to 46.7 to 71.2 MN/m2. In the central zone within the marginal area the individual glazings have tensile stresses in the core, which in the case of a glazing thickness of 2 mm amount to 38 to 67 MN/m2, while for a glazing thickness of 3 mm amount to 33 to 60 MN/m2. Such composite glazings have high strength in the marginal area and a low strength in the central zone. Therefore they have excellent characteristics both from the static standpoint and from that of accident safety.

Title: Method for measuring actual load at failure of optical fibre
Inventor: GLAESEMANN GREGORY S
IPC: G01N33/38
Filed: 1991-10-23
Abstract: ABSTRACT      Method wherein continuous indexed lengths of optical fiber are automatically measured for load at failure for each failure below a predetermined maximum stress.  A predetermined length of optical fiber is indexed.  The optical fiber is clamped at one or more clamp points along its length.  Increasing tension is applied to a first indexed length of optical fiber between at least one clamp point and a tension application means.  Increasing tension is applied between an initial value and the predetermined maximum load.  The increasing tension is measured during its application.  If failure occurs, the actual load at failure is detected while the increasing tension is being applied.  When failure does not occur, the first length of optical fiber is released and a second length of optical fiber is indexed to the position where increasing tension is applied to the second length between at least one clamp point and the tension application means.

Title: Process for the preparation of finely divided, water-swellable polysaccharide graft polymers
Inventor: HEIDEL KLAUS
IPC: C08F2/18
Filed: 1991-10-31
Abstract: ABSTRACT             A novel process for preparing polysaccharide graft polymers by semicontinuous reverse-phase suspension polymerisation, partial dewatering and crosslinking is disclosed.  The process comprises continuously adding an aqueous solution of at least par-tially neutralised, olefinically unsaturated carboxylic acid to a suspension of a polysaccharide in a nonpolar solvent, in the presence of a dispersant.  After from 75 to 100% of the solution have been added, an additional dispersant is added to reduce the viscosity of the suspension.  The additional dispersant is a compound selected from the group consisting of amphoteric ammonium compounds containing a (C6 - C20)alkyl radical, quaternary imidazolinium salts containing a (C6 - C20)alkyl radical and mix-tures thereof.  The process provides a uniformly fine product having a narrow particle size distribution and high absorbency for water and body fluids.  The product is particularly useful for incorporation into cellular, sorptive hygiene articles, such as disposable nappies, sanitary towels and patient undersheets.
